Three long, parallel, straight wires each carrying a 8.0 A current pass through the vertices
of an equilateral triangle (L = 8.0 cm) as shown in the figure below. Currents on wires B
and C are out of page while that of wire A is into the page. What is the x and y components
of the magnetic field vector at the point of the wire B? Give your answer in µT.

In the figure, point P, is at perpendicular distance R = 28.7 cm from one end of straight wire of length L = 14.6 cm carrying current i = 0.756 A. (Note that the wire is not long.) What is the magnitude of the magnetic field at P2? P R R L. Number i Units

Consider a long, horizontal Large Wire with current of 10 A running through it. We want to levitate a horizontal, thin, 0.50 m length of wire above it. If the thin wire has a mass of 10 grams, and a current of 300 mA, how far above the Large Wire will it hover (net force of zero) due to magnetic and gravitational forces? A. If the thin wire hovers above the Large Wire due to their magnetic fields, are their currents going the same direction, or opposite directions. Explain. B. Draw a diagram and label the directions of currents, and all other relevant quantities and vectors. C. Find the distance above the Large Wire the small thin wire will hover (net force of zero). D. Would your answers to parts A and C change if we wanted to find a distance below (rather than above) the Large Wire that the smaller thin wire could hover, due to their magnetic fields. Explain. Don't calculate any values but draw a new diagram and explain how this situation compares to the problem above.
Chapter 28, Problem 020 An electron is accelerated from rest through potential difference V and then enters a region of uniform magnetic field, where it undergoes uniform circular motion. The figure gives the radius r of that motion versus V¹/2. The vertical axis scale is set by rs= 4.0 mm, and the horizontal axis scale is set by V¹/2= 32.9 V¹/2. What is the magnitude of the magnetic field? r (mm) VI/2 V¹/2 (¹/2)
